Write the given sentence as an equation. Tim s age in 7 years will be three times what it was 19 years ago.

Hi,

Let's say x if the actual age of Tim.

In 7 years, he will be old of x+7

19 years ago, his age was x-19

So

x+7=3 * (x-19)

==>3x-57=x+7

==>3x-x=7+57

==>2x=64

x=64/2

==>x=32

Proof:

age=32

in 7 years: 32+7=39

19 years ago 32-19=11

and 39=3*11
